China's economy surged 10.9 percent year on year in the first half of 2006, the National Bureau of Statistics (NBS) revealed Tuesday, roaring ahead despite a slew of measures imposed by the government to ease investment growth.

Total gross domestic product between January and June reached 9.14 trillion yuan (1.14 trillion U.S. dollars), NBS spokesman Zheng Jingping told a press conference in Beijing Tuesday morning.

China's macro-economy presents "obvious overheating of investment" in the first half of this year, Wang Xiaoguang, a macroeconomics professor at the economic research institute of the National Development and Reform Commission, told Xinhua.

The NBS said total investment in roads, factory equipment and other fixed assets soared 29.8 percent, an increase of 4.4 percentage points from the same period of last year.

"The overheating is all-round, in nearly all industries and all regions of the country," Wang said, urging the government to tighten macro-control to contain the trend.

According to the NBS, the investment in urban areas in the past six months reached 3,636.8 billion yuan, increasing 31.3 percent or 4.2 percentage points higher, the highest growth since the second half year of 2004.

Stimulated by the surging housing demand, the total investment in real estate sector increased by 24.2 percent, or 0.7 percentage point higher over the same period last year.

In terms of different industries, the investment in heavy industry was up by 32.6 percent, of which the year-on-year growth of investment in coal mining and washing was a record high of 45.7 percent.

The country's soaring demand for energy resources drives the investment in extraction of petroleum and natural gas up 30.3 percent in the first half of this year, and investment in production and supply of electricity, gas and water went up by 17.5 percent.

While stimulated by the booming economic growth, the investment in railway transportation, the main vehicle to transport production materials in China, surged 87.6 percent in the first half of this year.

In addition, the year-on-year growth of investment in light industry was 41.2 percent, of which the investment in manufacturing of foods was up by 65.1 percent, and that in textile industry up by 40.6 percent.

Huang Huahua, Governor of Guangdong Province, said that the economy of Guangdong Province saw a rapid and rational development in the first half of this year.

In Jan-Jun, 2006, the GDP of Guangdong Province hit 1156.532 billion RMB, up 14.4 percent year on year. The value added of large industries reached 486.78 billion RMB, with an increase of 18.5 compared with the same time of last year.
